CarTech® Glass Sealing "42-6"

Generic Family: Iron - Wrought - Fe-Ni Alloy • Supplied by: Carpenter Technology Corporation

CarTech Glass Sealing "42-6" is nickel-chromium iron which has been developed to match the thermal expansion characteristics of 0120 glass.

An additional advantage of this alloy for glass-to-metal seals is the tight dark green oxide coating formed by wet hydrogen annealing at 1900/2200°F (1038/1204°C) for one hour. The oxide tends to flux with the glass and make it a vacuum tight seal if the surfaces are clean.

To obtain the necessary surface cleanliness, pickle in muriatic acid.

Applications:
CarTech Glass Sealing "42-6" has been supplied in strip form for glassed windows and television and CRT anode buttons. It has also been supplied in wire form for use in leads for compression seals.
